Trait CredentialProvider 

pub trait CredentialProvider:
    Debug
    + Send
    + Sync {
    type Credential;

    // Required method
    fn get_credential<'life0, 'async_trait>(
        &'life0 self,
    ) -> Pin<Box<dyn Future<Output = Result<Arc<Self::Credential>>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

Provides credentials for use when signing requests.

Implementors are responsible for fetching, refreshing, and returning a credential of an associated type (e.g. an AWS SigV4 key set, an Azure bearer token, or a GCP service-account token). The cloud-client crate ships ready-made implementations for every supported provider; see the per-cloud credential modules for details.

Required Associated Types

type Credential

The type of credential returned by this provider

Required Methods

fn get_credential<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Arc<Self::Credential>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Return a credential

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
